摘要
施工导流方案的合理选择对整个工程施工的顺利展开具有重要的意义。笔者以旺盛江水库的南流江大渡槽的施工导流工程为例,详细介绍了筑岛+过水围堰+钢栈桥、筑岛+埋管+钢栈桥、水中架设钢平台和分期导流围堰等4种施工导流方案,并从工程基本因素和导流建筑物施工等方面进行比选,推荐采用筑岛+过水围堰+钢栈桥方案。水力计算和施工工法的分析结果表明,该推荐优选方案在该实际工程中是具有可靠性、可行性和施工便利性的。
The reasonable selection of construction diversion scheme is of great significance to the smooth development of the whole project. Taking the construction diversion project of Nanliu River Aqueduct of Wangshengjiang Reservoir as an example, the author introduces four construction diversion schemes in detail,such as island construction+overwater cofferdam+steel trestle, island construction+buried pipe+steel trestle,steel platform erection in water and staged diversion cofferdam, and compares them from the basic factors of the project and the construction of diversion buildings. The scheme of island construction+overwater cofferdam+steel trestle is recommended. The analysis results of hydraulic calculation and construction method show that the recommended scheme is reliable, feasible and convenient in the actual project.
